Inspection Procedure

WARNING: This page is about a different car, the 2005 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.

OPERATION CHECK
1. If the power slide door does not operate when trying to open it, proceed to A.
2. If the power slide door does not operate when trying to close it, proceed to B.
1. B: Go to step 3
2. A: Go to next step
CHECK SLIDE DOOR CLOSER SYSTEM
1. Check if the slide door closer system operates.
1. NG: GO TO CLOSER SYSTEM (See SLIDE DOOR CLOSER SYSTEM )
2. OK: Go to next step

READ VALUE OF HAND-HELD TESTER

Using the hand-held tester, check the DATA LIST for proper functioning of the handle operation detect switch.
Standard (Power slide door ECU LH):

DATA LIST ITEM REFERENCE

Item	Measurement Item/Display (Range)	Normal Condition	Diagnostic Note
HANDLE SW	Handle operation detect switch signal /ON or OFF	ON: Slide door inside/outside handle is pulled OFF: Slide door inside/outside handle is not pulled	-

OK: Go to step 6
NG: Go to next step

INSPECT SLIDE DOOR LOCK REMOTE CONTROL SUB-ASSY LH (HANDLE OPERATION DETECT SWITCH)

Inspect the resistance of the switch.
Standard:
